Problems solved by technology

[0002] Bone china has the characteristics of good translucency, thin carcass, light porcelain and good thermal stability. Its unique secondary firing process determines its high regularity and bright and soft glaze. It is an international The first choice of high-end porcelain in China, the fly in the ointment is that bone china has always been dominated by white, with a single color
[0003] Lu celadon, which appeared in the early 1980s, is popular with people for its emerald green color, but the quality of Lu celadon is not good, the product is clumsy, the carcass is thick, and the translucency is poor. Larger, the color difference of the product is serious, and the production scale has not been formed for many years, which limits the development of this product

Embodiment 1

[0023] Bone emerald porcelain of the present invention, batching weight percent is composed of:

[0024] 33% bone meal, 9% feldspar, 16% porcelain powder, 26% Datong, 8% Longyan soil, 6% black mud and 2% Laiyang soil, plus 0.10% copper oxide and 0.15% iron oxide.

[0025] Put the above-mentioned ingredients into a ball mill according to the conventional method, then press filter, and then use a vacuum mud trainer to refine the filter cake into a mud bar with a water content of 21%, and roll it into a 6-inch flat disc with a rolling machine, at 1270 ± 5 Bisque firing at a temperature of ℃, and then apply lead-free frit glaze (the weight percentage of lead-free glaze is composed of: SiO 2 55%, AI 2 o 3 10%, KNaO10%, Li 2 O1%, BaO10%, ZnO5%, B 2 o 3 9%), firing at a temperature of 1170±10° C. to obtain the emerald-green bone emerald china of the present invention.

Embodiment 2

[0027] Bone emerald porcelain of the present invention, batching weight percent is composed of:

[0028] Bone powder 35%, feldspar 10%, porcelain powder 18%, Datong 22%, Longyan soil 8%, black mud 6%, Laiyang soil 1%, plus copper oxide 0.13% and iron oxide 0.14%.

[0029] Put the above-mentioned ingredients into a ball mill according to the conventional method, then press filter, and then use a vacuum mud refiner to refine the filter cake into a mud bar with a water content of 21%, and use a rolling machine to press the flat plate. Bisque firing, then apply lead-free frit glaze (the weight percentage of lead-free glaze is composed of: SiO 2 55%, AI 2 o 3 10%, KNaO10%, Li 2 O1%, BaO10%, ZnO5%, B 2 o 3 9%), firing at a temperature of 1170±10° C. to obtain the emerald green bone emerald china of the present invention.

Embodiment 3

[0031] Bone emerald porcelain of the present invention, batching weight percent is composed of:

[0032] 32% bone meal, 9% feldspar, 18% porcelain powder, 25% Datong, 9% Longyan soil, 5% black mud and 2% Laiyang soil, plus 0.13% copper oxide and 0.14% iron oxide.

[0033] Put the above-mentioned ingredients into a ball mill according to the conventional method, then press filter, and then use a vacuum mud refiner to refine the filter cake into a mud bar with a moisture content of 22%, and press a 5-inch bowl with a rolling machine. Under biscuit firing, then apply lead-free frit glaze (the weight percentage of lead-free glaze is composed of: SiO 2 55%, AI 2 o 3 10%, KNaO10%, Li 2 O1%, BaO10%, ZnO5%, B 2 o 3 9%), firing at a temperature of 1160±10° C. to obtain the emerald green bone emerald china of the present invention.
